As I was processing a batch of scrap lead, I had a few panfulls had a gold colored layer on the top. I skimmed the alloy several times, surface would be silver for a minute or so but would return to gold. Seemed more like the surface was oxidizing rather than a contaminant rising to the surface. Alloy temp was 720.
I raised the temp to 800 and the surface turned blue.
Ingots had a very slight golden tint.
Not trying to upstage the Lone Ranger here but perhaps I should save this alloy for pistol bullets. Can't hit anything with that anyway.
"Insert image" button isn't working for me, advice?
